I created a form for data entry that contains a drop down list from which users choose one of 10 values. Now a client wants to add an 11th value to be selectable but I get:
"There is data for this field in the database. The field settings can no longer be changed."
Is there a preferred way for creating these lists in the future so that
1. They come from a database lookup rather than someone typing in a list of values
2. Entries can be added as needed?
